well-known port list

IANA is responsible for assigning port numbers to specific uses. The well-known ports are those in the range 0-1023. On Unix-derived operating systems, opening a port in this range to receive incoming connections requires root privileges. Registered port numbers are those in the range 1024-49151. Port numbers in the range 49152-65535 are private or dynamic ports, not used by any defined application.
IANA does not enforce this; it is simply a set of recommended uses. Sometimes ports may be used for different applications or protocols than their official IANA designation. This misuse may, for example, be by a Trojan horse. Or it may be a common program that you use every day, but that never got an IANA registered port or port range.

See the IANA list of port assignments for a full list.

DHCP : Dynamic Host Configuration Protocol DHCP is a client-server networking protocol. A DHCP server provides configuration parameters specific to the DHCP client host requesting, generally, information required by the host to participate on the Internet networ Dynamic Host Configuration Protocol

TFTP : TFTP is a very simple file transfer protocol akin to a basic version of FTP. TFTP is often used to transfer small files between hosts on a network, such as when a remote X Window System terminal or any other thin client boot Trivial File Transfer Protocol

Finger : The finger protocol is a simple network protocol based on RFC 1288 The Finger User Information Protocol . Typically the server side of the protocol is implemented by a program "fingerd" (for finger daemon), while the client side is implemented by the "nam Finger
